CEMENTING-MACHINE.

Specification of Letters Patent.

Patented Jan. 16, 1906.

To all whom it may concern:

Be it known thatI, WILLIAM F. LAUTEN- SOI-ILAGER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in-Cementing-Machines, of which the following is a specification.

My invention relates to a' cementing-machine.

One of the objects of the invention is to provide a cement receiving and distributing roll having its periphery formed of a glazed surface.

Another object of my invention relates to the driving mechanism for rotating the cementing-roll.

Another object of my invention is to provide detachable cement-reservoir and rollscraper, whereby the parts can be readily removed for cleaning, and, further, enabling the cement-reservoir through its detachable means of having a pivotal movement toward the cement-distributing roll, thereby assuring a uniform feeding action of cement upon the periphery of the 13011 when the valve of the reservoir is opened.

Another object of my invention is to provide a valve and adjusting mechanism for the cement-reservoir, whereby the opening can be delicately regulated, so as to insure the proper delivery of cement, which varies in consistency, so as to insure under all conditions a proper'delivery and spreading of the cement.

Other features of the invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which Figure 1 is a central vertical section of my apparatus, partly in elevation. Fig. 2 is an end elevation of the same with the standard or base omitted. Fig. 3 is a perspective view of the Wiperof the cement-distributing roll.

Fig. 4 is a front elevation of the cement-res ervoir. Fig. 5 is an enlarged section on line as m, Fig. 2. Fig. 6 is an enlarged section on line w to, Fig. 4.

A represents the base of the frame provided with an upwardly-extending standard or support A, to which is secured a yokeshaped bracket or support B, upon which the various parts are j ournaled and supported. 1 represents a shaft journaled in bearings formed integral with the bracket B. Upon this shaft 1 is fixed a and distributing roll 2. This roll is driven in a direction toward the wiper 28, Fig. 2, by the following mechanism: 3 represents a gear upon shaft 1 and pinned to the hub of the roll 2 and in mesh with a pinion 4, out upon the stud-shaft 5, j ournaled in an eccentric bushing 6, said eccentric bushing being supported in a bearing formed integral with the bracket B. This eccentric is provided for a convenient machining, rendering it possible to adjust the pinion in proper driving engagement with the gear-wheel. This shaft 5 projects outwardly, the free end being provided with a loose pulley 7 and a tight pulley 8. Thus as motion is imparted to the tight pulley 8 it will revolve shaft 5, pinion 4, gear 3, and roll 2. It will be seen that this construction of standard and driving mechanism renders possible the construction of a neat, durable, and compact machine with the driving-gears within the rim of the roll 2, the tight and loose pulleys being the only members of the driving mechanism that are exposed.

I have found by experience that it is necessary in the perfect operation of the machine to coat the periphery of the roll 2 with a material presenting a hard glazed surface, for it has been found that when fibrous material, such as linings of a shoe, are presented to the surface of the roll for applying cement thereto-that is, to the lininga small amount of lint is deposited upon the roll. This is readily removed from the hardened surface by a suitable wiper, to be hereinafter described. It has been found that when a surface other than a glazed surfaceas, for instance, say, a rubber belt or the likeis secured to the periphery of the roll such lint will adhere to the roll and cannot be taken up by the wiper, owing to the flexibility of such roll, and will pass under the wiper and in the course of a short time by an extended use of the machine will greatly vary the plane of the surface of the roll, thereby causing an irregular feed or deposit of cement upon the roll and also cause the same to receive a surplus of cement at various surface positions, which surplus cement frequently coagulates and drops to the floor, causing a loss of cement,

cement receiving making it di'fli cult to keep the machine clean, and, in fact, rendering the machine useless. By coating the roll with a glazed surface I overcome this serious objection and, in fact, am enabled to maintain a clean machine and roll having a deposit of glue upon the surface only of the required and desired thickness. 9 represents such material, which is preferably composed of a coating of hard rubber having a glazed finish.

10 11. represent arms fixed to the bracket B, the free ends of which are provided with a rod 12, journaling in said arms and upon which rod the cement-reservoir 13 is pivotally supported by means-of ears 1 1.

15 represents the base portion of the reservoir having an inclined face portion 16, adapted to bear against the periphery or surface of the roll 2. This surface is provided with the channel 17, extending the entire width of the reservoir, forming a cement-receiving port for such surplus cement as may possibly escape from the wiper 28. 18 represents distributing-channels leading from. the channel 17 to the mouth of the valve 19, whereby the surplus cement thus caught up will be com mingled with the fresh supply deposited.

upon the surface of the roll when the valve is opened.

The construction of the valve is as follows: 19 represents a valve of tubular form, hav ng a cut-away portion 20, whereby an abrupt shoulder 21 is formed, said shoulder being adapted to engage against. a shoulder 22, formed on the base portion of the reservoir, whereby when the parts are brought into engagei'nent with each other they will be securely locked and form a very effective seal. The valve is seated in the base portion of the reservoir and held in position by the following instrumentalities: 23 represents valveseats for the cylindrical valve 19. (See Fig. 5.) 24 represents a boss formed on the base portion of the reservoir and extending the entire length thereof. 25 represents a plate secured to said boss by means of screws, said plate performing the office of holding the valve securely in position. The free end of said plate has an inward spring-like tension, whereby the valve will always be held against its bearing parts, preventing any leaking at such points. 26 represents a packing inserted between the valve and boss and held in position by the plate 25, thereby preventing any leakage at suchpoint and also forming an abutment for the valve. 27 represents a lever fixed to the valve at one end, by means of which thevalveopening is controlled. By this construction of valve it will be seen that the parts are readily removable, enabling the same to be easily cleaned, as the class of cement used is very difficult to handle and when it becomes dry from non-use renders the device almost entirely impractical, requiring the same to be cleaned, which is a very difficult operation, as the parts in many instances are required to be sandpapered before they can be brought or placed back into their operating positions. With my construction of valve I overcome these objections, as it is impossible for the cement to per meate into the valve-seats. By making the cylindrical well below the outlet at 21 a body of cement is maintained below the dischargepoint,which prevents the hardening of cement at the point of discharge, insures a free flow thereof, and is the preferred form of construction. It will also be noticed that the position which the valve and reservoir assume with relation to the roll is such that the valve is opened to a greater breadth than the thickness of cement applied upon the roll. This I regard. as a very important feature in obtaining a uniform spreading of cement upon the roll-surface and which I have found by experience can. only be accomplished by a free supply, and with my construction I produce such results without causing a surplus of cement to be supplied to the roll.

28 represents a wiper provided with depending ears 29, adapted to be detachably supported upon the rod 12. This wiper is provided with a knife edge 30, hearing against the surface of the roll 2, the rearward portion of the wiper draining into the reservoir 13. This reservoir may be provided with a screen at such draining-point to catch up any residue. The wiper may have a flexible head instead of the knife-edge.

Having described my invention, I claim- 1. A cementing machine comprising a frame, a hollow spreading roll journaled thereon, a driving-shaft ournaled on said frame and extending into said hollow roll, means for rotating said roll, a cement-reservoir pivotally supported on said frame, having a distributing portion bearing against the surface of the roll, and a hollow cylindrical valve seated within said reservoir, and means for rotating said valve to adjust the delivery of cement, substantially as described.
